Mirror Control Circuit Range/Performance Problem
Problem with the power mirror control circuit's range or performance.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The power mirror isn't moving as far as it should, likely due to a bad connection or a faulty switch.
What the computer is actually seeing
The body control module (BCM) monitors the voltage feedback from the mirror position sensors. It expects to see a full range of motion and proper resistance values when the mirror controls are manipulated.
What a healthy reading looks like
Expected resistance values from mirror sensors should be between 5 to 10 ohms when moving the mirror, and the voltage should be near 12 volts when active.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the mirror switch for any signs of damage or corrosion. Is it functioning properly? (Try toggling and listening for clicks) - If not, replace the switch.
- 22. Check the wiring harness and connectors at the mirror for wear, breaks, or corrosion. Are they intact and clean? - If damaged, repair or replace the wiring harness.
- 33. Measure voltage at the mirror connection when the switch is activated. Are you seeing around 12 volts? - If not, trace back to the BCM for further issues.
- 44. Test the mirror positioning motor directly with a known good power source. Is it operating correctly? - If it fails to respond, replace the motor.
Common causes
- Faulty mirror control switch
- Wiring issues in the mirror circuit
- Bad mirror positioning motor
- Corrosion in connectors or broken wires

Frequently asked questions
Can I drive my vehicle with this code active?
Yes, but you will have limited functionality for adjusting your mirrors.
What happens if I ignore this code?
Ignoring it may lead to further electrical issues or a complete failure of the mirror adjustment system.
Why does this code keep coming back after repairs?
This can happen due to underlying wiring issues or a faulty BCM that continues to send incorrect signals.
